The distinguishing characteristics of the plasma membrane are its exposed proteins

R E Gates et al. Biochem J. 1975 May.

Abstract

The exposed proteins of the plasma membrane of normal human lymphocytes and platelets were labelled by using the lactoperoxidase macromolecular probe system. The labelled components were separated into molecular-weight classes by sodium dodecyl sulphate--polyacrylamide-gel electrophoresis. In contrast with the report by Tanner et al. (1974), a comparison of the two cell types showed that the major labelled components in both cell types were glycoproteins and were not identical. It is concluded that the exposed proteins are probably the most distinguishing characteristic of the plasma membrane of differentiated cell types.
